Title Study of the spectral soft excess in high luminosity transient pulsars

Description Many accreting X-ray pulsars show a low-energy soft excess in their spectra, whose origin is still unclear. The study of this feature is essential to cast light on the physical processes on-going in these sources. Due to the low absorption, the transient pulsars in the SMC, which can reach high luminosities (Lx>1E38 erg-s), are ideal targets for these studies. Very recently, we obtained an observation of RX J0059.2-7138 in outburst: it allowed us to detect and study at an unprecedented level of detail its soft excess, discovering several emission and absorption features, which provide strong constraints on the source emission processes. We propose a ToO observation of another transient pulsar in the SMC, in case of a bright outburst, in order to characterize its soft excess.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
